This paper documents the presence of Osensitive sectorsO in Free Trade Agreements, defined as sectors for which the within-FTA tariffs remain positive. The paper includes some brief theoretical discussion of the welfare implications of these, but the main emphasis is on reporting two measures of this phenomenon for countries in FTAs that entered into force between 1994 and 2003. One measure is the percentage of tariff lines that remain dutiable, and the second is the change, from before the FTA to after, in the average maximum (across 6-digit products) positive tariffs. Both measures are derived from data in the UNCTAD TRAINS database, and are then related to measures of country characteristics that might explain them. Low per capita GDP countries tend to have larger fractions of dutiable tariff lines, while higher income countries tend to post larger increases in average maximum positive tariffs. Both suggest that the favored treatment of sensitive sectors is undermining the potential gains from trade that FTAs provide.

自由贸易协定中的敏感部门

本文记录了自由贸易协定中不敏感部门的存在，自由贸易协定中FTA内的关税保持为正。本文对这些福利的含义进行了简要的理论讨论，但主要重点是针对1994年至2003年生效的自贸协定中的国家报告了针对这一现象的两种措施。一种措施是仍应课税的关税税率的百分比。 ，第二个是从FTA之前到之后的平均最高关税（跨6位数字产品）的正关税变化。两项措施均来自贸发会议TRAINS数据库中的数据，然后与可能解释它们的国家特征措施有关。人均GDP较低的国家/地区的应税关税税率往往较高，而收入较高的国家往往会在平均最高积极关税上大幅度提高。两者都表明，对敏感部门的优惠待遇正在损害自贸协定提供的贸易的潜在收益。
